spoke with devin and honestly they have me frazzeled. the entire holdup is locating a proper circlip for the slk32 stub axles. the srt-6 is a non issue as is any post 2004 n/a version. so instead of proceeding with the prototype and finding circlips during the build or letting us (slk32 owners) deal with it they are holding everything up until a working clip is found. KRAZY!!
i have some part # that im going to try and locate and see if they will work. if anyone can source a circlip .100 to .120 thick with a flat inside surface this should end the problem. i would happily pay for a few of them to send to devin to try.
